CHARLES C. CLARK, OF DAVENPORT, IOWA.

GAS-BURNER DEFLECTOR.

Application filed July 6, 1928. Serial No. 290,815.

The object of this invention is to provide an improved auxiliary gasburner or flame deflector, adapted to be placed above or upon thestandard gas burner of stoves, heaters or furnaces.

Another object is to provide an improved burner whereby the gas afterleaving the regular burner is permitted to combine with such quantitiesof oxygen as will form a mix,

ture capable of giving the maximum heat content upon combustion.

Further objects are to so construct the burner of a convexo-concavoconfiguration as to cause the flame to be concentrated upon the articleto be heated, to increase the amount of air or oxygen which is consumedwith the gas, to reduce the time required to heat an article and tofurnish a device which retains the heat after the flame has beenextinguished.

The primary object of this invention is to construct the flame deflectorwith radial segments forming passageways whereby the gas and air areadmixed and conducted to the orifices in the proper proportion forcorrect combustion, thereby obtaining more heat units. 1 I

The improvements may be more readily understood by reference to thedrawing wherein:

Fig. 1 is a plan view of the cap. r

r Fig. 2 is a section taken on the line 22 of Fig. 1 showing theconvexo-concavo configuration.

Fig. 3 is a section taken on the line 33 of Fig. 1.

The burner or cap may be cast or stamps from metal such as iron,aluminum, copper, brass or any suitable material which will withstandthe heating and cooling temperature encountered. The body of the devicedesignated by the numeral 10 is of general convexo-concavo outline; ithas been found from an exhaustive trial of devices of this type that theconvexo-concavo outline is superior to that of a truncated coneor ofaflat type burner. The body 10 is provided with alternately raised andlowered segments or ribs, 11 and 12. These segments form radiallydisposed passageways 13 whereby as the leaves the regular burnerit isconducted to the orifices 14 or 15. I The conveXo-concavo outline of theburner causes the gas to travel in whirling eddies, thereby sucking inthe maximum amount of air thru the openings 16. These openings 16 areprovided due to the raised segments 11 which continue to the very edgeof the burner.

The creation of these eddies gives a steady flow of combustive materialto the orifices and prevents the setting up of cross currents due to thestream of gas from the burner striking the cap at too sharp an angle.

The lowered ribs 12 permit the making of the cap with a minimum weightof material and allow a uniform thickness to be maintained so that inheating and cooling of the caps it will not break or warp due tointernal stresses.

' The side orifices 14 are arran ed about midway up the body 10 andcentrally disposed in the ribs 11 and 12. The central orifice 15 is theprincipal place of combustion and throws an intense stream of heat uponthe article.

The formation of the cap with the ribs 12 extending to the outerperiphery'and all terminating in the same horizontal plane, when the capis placed upon the burner, permits a cap of the same size to be usedupon the various sizes and types of gas burners. These ribs 12 act as ameans of maintaining the cap the proper distance above the gas burner topermit the entrance of air into the openings 16. WVithout thesedepressed ribs when the cap is placed upon some types of gas burners itsettles down close to the burner preventing 'the entrance of air andcausing incomplete combustion of the gas, which in turn results in thegiving off of poisonous carbon monoxide.

It is to be understood that the cap may be made in any size ormaterialdesired and is adaptable wherever gaseous fuel is burned.

WVhat I claim is:

1. A flame deflector cap for gas burners, including a body portioncomposed of radially disposed alternately raised and lowered connectiugsegments, said alternately disposed segments providing radially disposedpasways whereby complete combustion of the is facilitated, and anorifice centrally disposed in said body.

2. A gas burner, comprising a convexoconcavo body portion formed of aplurality of alternately raised and lowered radially disposed segments,the raised segments at the periphery of the burner outhne an opening forthe combustion gases, at central orifice and a A plurality ofintermediate orifices circumfer- 5 entially disposed 1n said raised andlowered segments.

3. In a flame deflector cap for gas burners,
